exchange.IO(k, token, budget, options)

Examples

• Pick a SOL/USDC pool for a budget of 100 USDC.

  
      javascript
      
      
  function main() {
      var pool = exchange.IO("lp.select", "SOL", 100, {quote: "USDC"})
      if (!pool) {
          Log("Selection failed:", GetLastError())
          return
      }
      Log("Picked:", pool.dex, pool.id, "fee", pool.fee / 1e4 + "%", "reason:", pool.reason)
  }
  

• Pick only among Raydium and Orca pools.

  
      javascript
      
      
  function main() {
      var pool = exchange.IO("lp.select", "SOL", 100, {quote: "USDC", protocol: ["raydium", "orca"]})
      if (!pool) {
          Log("Selection failed:", GetLastError())
          return
      }
      Log(pool.dex, pool.id, "tickSpacing", pool.tickSpacing,
          "24h volume", Math.round(pool.volume24hUsd))
  }

Selection rule

1. The lp.pools rows are filtered; nothing left is an error.
2. The floor is the larger of $5000 and budget in USD, with budget valued at the USD price of the first pool's quote token.
3. Among pools whose USD TVL reaches the floor, the one with the largest 24h volume wins; if none of them has volume data, the largest TVL; if no pool reaches the floor, the largest TVL of all.

reason names the case, as in highest 24h volume among pools with TVL >= $5000, largest TVL among pools with TVL >= $5000 (no volume data) and no pool reaches $5000 TVL; picked the largest.

exchange.IO("lp.plan") picks the pool by the same rule when pool is not given (taking fee, protocol, binStep and tickSpacing from the plan parameters). The busiest pool is not necessarily the best for a position: the fee and the price grid (binStep, tickSpacing) decide the fee income and how precise the range can be.
